BOTTLE-SEAL.

SPECIFICATION forming part of Letters Patent N 0. 775,651, dated. November 22, 1904. Application filed January 27,1904. Serial No. 190,891. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM E. HEATH, a citizen of the United States, residing at Baltimore city, Maryland, have invented certain new and useful Improvements in Bottle-Seals; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain improvements in sealing devices for receptacles, and more particularly relates to improvements in caps for bottles, jars, and the like.

An object of my invention is to provide an exterior sealing cap or ring device adapted to be bent or otherwise looked under a bottle-shoulder and to provide the same with improved means for releasing the ring or cap from the bottle or breaking the seal without requiring the employment of a tool or other separate extracting or releasing device. My invention consists in certain novel features of construction and in combinations or arrangements of parts, as more fully set forth hereinafter.

The further objects and the nature of my invention will be readily understood by those skilled in the art in the light of the following explanations of the construction shown in the accompanying drawlngs merely as an example for purposes of illustration of one device from among others within the spirit and scope of my invention.

Referring to the accompanying drawings, Figure '1 is a perspective view of the neck portion of a bottle sealed by a device in ac cordance with my invention. Fig. 2 is a perspective View of the neck portion of a bottle having my invention applied thereto, the pull or finger piece being shown elevated or swung up to operative position to receive the necessary pulling force for accomplishing the initial release of the cap from the bottle. Fig. 3 is a perspective view of the neck portion of a bottle, showing the cap in the position it assumes during the first portion of the releasing operation. Fig. 4c is a plan View of the exterior cap with the flange flattened out or showing the cap just prior to the bending down of the flange thereof. Fig. 5 is a vertical sectional View of the bottle-neck and sealing device, showing the sealing device before it is subjected to sealing pressure and before the exterior cap or ring is bent or locked on the bottle-shoulder. Fig. 6 is a section corresponding to Fig. 5, but showing the seal effected and the exterior cap locked under the bottle-shoulder. Fig. 7 is a detail perspective view showing the parts of the sealing device or cap separated from each other.-

In the drawings, a is the neck portion of the bottle,having the top-sealing edge 6 around its mouth.

0 is an annular bead around the exterior of the top portion of the neck of the bottle and forming the exterior locking-shoulder of the bottle, which in the present instance is shown as an annular shoulder, although I do not wish to limit all features of my invention to employment in connection with an annular shoulder. In the specific example shown the bead c is located a short distance below the top-sealing edge 6, so that the exterior diameter of the bottle-neck is reduced above the bead c. However, I do not wish to limit all features of my invention to this detail.

d is the sealing medium, composed of any suitable compressible or soft, preferably impervious, material, which can be treated, if desired, to render it impervious. This sealing medium can be composed of various materialssuch, for instance, as cork or a suitablyprepared fabric or pulp material. The sealing medium shown is in the form of a flat circular disk which is imperforate and is of a diameter to close the bottle-mouth and rest on and project beyond, if necessary, the top annular edge Z). In the specific example illustrated I show this sealing-medium disk d carried by or faced throughout its top surface by an imperforate circular flat metal disk 0, preferably, although not necessarily, formed with a depending annular flange, rendering said metal disk somewhat cup-shaped to receive and hold the sealing-medium disk 05. However,,I do not wish to limit my invention in all features to the flanged disk 6.

r The sealing-medium disk is located concentrically within and is adapted to be held tightly compressed on and around the bottle-sealing edge 6 to maintain the tight seal by an exterior somewhat stifl' metal sealing-cap This exterior looking or sealing cap is preferablyformed from one piece of comparatively thin sheet metal and consists of the flat approximately annular ring-like top located immediately above the sealing edge I) of the bottle and the vertical depending flange g and the pull-or finger releasing piece, portion, or tab k. The depending flange g has a diameter enabling the exterior cap to snugly receive the sealing-medium disk d and its disk 6 and to enable the flange to pass down'around the bottle-bead c. This flange g is of such length that when the parts have been assembled on the bottle-neck, as shown in Fig. 5, and the necessary pressure is applied to tightly compress the sealing medium between the edge 6 of the bottle and the annular top of the cap the flange can be bent, spun, or otherwise turned under the bottle-locking shoulder to a sufiicient extent to maintain the exterior cap in'its position, holding the sealing medium tightly compressed to maintain the necessary or desired tight seal. In order to permit the ready release of this exterior cap, I dividethe flange g at several points, preferably so that the cap will have the transverse or usually diametrical bending-line. In the specific example illustrated I divide the flange g at least about to the top of the cap by diametrically opposite vertical slits or slots i, and I preferably enlarge these slots at their lower ends by notching at f the lower edge of the flange g, so that the lower end of the flange Q will not lock under the bottle-shoulder immediately adjacent to the slots At a point about midway between the slots z I preferably so cut, notch, (see K9,) or otherwise form the flange 9 so that it will not turn or look under the bottle-shoulder. I provide this exterior cap with a releasing device attached or joined to the cap immediately above the notched or non-locking portion 76, so that when the cap is locked to the bottle sufiicient upward pull on said releasing device will cause the initial release of the cap byreason of the flange g pulling or slipping past the locking-shoulder of the bottle on both sides of the notchk, so that said half of the cap formed with the notch k will bend upwardly on a diametrical line between the slots 71, thus enabling the cap to be pulled laterally or tilted completely from the bottle-neck. It is obvious that the notched portions j will assist in the easy ready release of the cap from the bottle, and thus when the half of the cap having the notch k has been released from the locking-shoulder that the other half of the cap can be readily slipped or pulled from the bottle. The notched or cut-away portion Z0 permits the ready initial release or starting of the unlocking or releasing movement of the cap. While as at present advised by experience I deem it desirable that the cap be not locked at a point below the application of the releasing-pull, yetI do not wish to so limit all features of my invention. This releasing device can be constructed and arranged in various ways under the broad features of my invention.

In the specific example illustrated I show said releasing device composed of the sheetmetal disk 71, cut out from the top of the cap f and connected thereto by the neckl at a point above the notch 70. I show this fingerpiece or pull device formed with irregularities m m to afford a finger hold or grip, and

the depression m engages the disk 0 when the cap is compressed and locked, and there- I by holds the finger-piece it slightly above the plane of the top of the cap f, (see Fig. 6,) so that the finger of the operator can so engage the edge of the finger-piece h as to readily bend the same up to the position shown in Figs. 2 and 3. These irregularities m m can be formed in any suitable manner and of any suitable or desirable form, usually by indenting or corrugating the disk of the fingerpiece, for instance, about as shown. The downwardly-pressed indentation or indentations m will engage the top surface of the disk 6 to slightly elevate the disk of the finger-piece above the plane of the top of the cap. The operation of applying the cap, as well as the operation of releasing the same through the medium of the pull-piece, will be readily understood by the foregoing description.

The chuck, which engages the cap to compress the seal during the sealing operation,

need only engage or apply pressure to a flat annular portion of the top of the cap.

By cutting out the top of the cap so that, the cap is somewhat ring-like in form the cap can more easily bend along the diametrical bending-line during the releasing operation than where the top of the cap is closed, and hence I do not consider it necessary to extend the slots into the top of the cap, if such be necessary, where the top of the cap is closed.

I do not wish to limit my invention to the form and arrangement of the pull-releasing device nor to the manner of attaching the same, and it is obvious that various modifications might be resorted to in the forms, constructions, and arrangements of the parts shown without departing from the spirit andscope of my invention, and hence I consider" myself entitled to all such variations as fall within the spirit of my invention.

What I claim is 1.' A cap for a bottle or the like having a depending locking-flange severed to form a transverse bending-line and a releasing device consisting of a pull-piece integral with the cap and arranged at the top thereof.
